Study of Marine Nuclear Steam Turbine Plant Simulation

A two-phase flow simulation model for marine nuclear steam turbine plant is established in the paper.By means of the model,the dynamic characteristics of marine nuclear steam turbine plant under the rapidly varying duty working conditions is calculated and analyzed.The result indicates that the model can simulate the varying duty working characteristics of nuclear steam turbine plant accurately,and meets the needs of simulation analysis work on secondary system of nuclear power plant.The model has been applied to two types of marine nuclear power plant training simulator successfully,and is meaningful to the training of operators and validating of operating rules.
